California's water woes are far from over. A sobering new report from the National Resources Defense Council said California is among 14 states most at risk for a water shortage by the middle of the century.

The report said warmer temperatures are depleting water supplies in the state as the demand for water rises.

The environmental group found that rising temperatures are taxing aquifers that are already stressed by heavy agricultural and consumer use.

The report did not factor in future improvements in water supply systems.
